There is disclosed a hybrid system for generating free energy from dam-water by integrating giant turbines with piezoelectric nanogenerators and solar cells. This three-in-one generator harnesses electrical energy from solar and mechanical energy. Strategically positioned large-scale turbines convert the kinetic energy of water flow into electrical energy. Concurrently, integrated piezoelectric nanogenerators transform mechanical stress from turbine operations into electrical energy via the piezoelectric effect.
